Engineering Design Practice Tests

These Grade 8 Science practice tests cover problem definition, criteria, constraints, brainstorming, prototypes, testing, iteration, forces, materials, data analysis, safety, accessibility, sustainability, and engineering trade-offs.

Skills covered

  • Distinguishing criteria, constraints, trade-offs, and design requirements
  • Applying prototypes, fair tests, repeated trials, and evidence-based iteration
  • Connecting material properties, forces, energy, and structure to design performance
  • Evaluating safety, accessibility, life-cycle impacts, and sustainability
  • Using data to compare solutions and justify an engineering conclusion

How to use these practice tests

First identify the design goal and the limits. Then determine what should be measured, compare the evidence with the criteria, and decide whether the next step is to select, improve, or retest the prototype.

1. QuestionMultiple choice

What is the first step in an engineering design process?

Please select an answer first.

Correct answer: A

The correct answer is Define the problem and identify the need.

  1. Identify the design problem: Determine the goal, criteria, constraints, materials, users, and evidence described in the situation.
  2. Evaluate the design process: Engineers begin by identifying the problem, need, users, and desired outcome.
  3. Check the evidence: The correct choice is Define the problem and identify the need.

Engineers begin by identifying the problem, need, users, and desired outcome.

2. QuestionMultiple choice

What are criteria in an engineering design problem?

Please select an answer first.

Correct answer: B

The correct answer is The goals a successful solution should meet.

  1. Identify the design problem: Determine the goal, criteria, constraints, materials, users, and evidence described in the situation.
  2. Evaluate the design process: Criteria describe what the solution should do or how well it should perform.
  3. Check the evidence: The correct choice is The goals a successful solution should meet.

Criteria describe what the solution should do or how well it should perform.

3. QuestionMultiple choice

What are constraints?

Please select an answer first.

Correct answer: C

The correct answer is Limits such as cost, materials, time, size, or safety requirements.

  1. Identify the design problem: Determine the goal, criteria, constraints, materials, users, and evidence described in the situation.
  2. Evaluate the design process: Constraints limit the possible solutions and can include available resources, time, safety, and size.
  3. Check the evidence: The correct choice is Limits such as cost, materials, time, size, or safety requirements.

Constraints limit the possible solutions and can include available resources, time, safety, and size.

4. QuestionMultiple choice

Why do engineers brainstorm multiple solutions?

Please select an answer first.

Correct answer: D

The correct answer is Different ideas can be compared before selecting a design to test..

  1. Identify the design problem: Determine the goal, criteria, constraints, materials, users, and evidence described in the situation.
  2. Evaluate the design process: Generating several possible solutions supports comparison and can reveal a stronger approach.
  3. Check the evidence: The correct choice is Different ideas can be compared before selecting a design to test..

Generating several possible solutions supports comparison and can reveal a stronger approach.

5. QuestionMultiple choice

What is a prototype?

Please select an answer first.

Correct answer: A

The correct answer is A model or early version used to test a design idea.

  1. Identify the design problem: Determine the goal, criteria, constraints, materials, users, and evidence described in the situation.
  2. Evaluate the design process: A prototype allows engineers to test function, materials, and performance before building a final product.
  3. Check the evidence: The correct choice is A model or early version used to test a design idea.

A prototype allows engineers to test function, materials, and performance before building a final product.

6. QuestionMultiple choice

Why do engineers test a prototype?

Please select an answer first.

Correct answer: B

The correct answer is Testing reveals how well it meets criteria and what should be improved..

  1. Identify the design problem: Determine the goal, criteria, constraints, materials, users, and evidence described in the situation.
  2. Evaluate the design process: Evidence from testing shows whether the prototype works and identifies weaknesses or trade-offs.
  3. Check the evidence: The correct choice is Testing reveals how well it meets criteria and what should be improved..

Evidence from testing shows whether the prototype works and identifies weaknesses or trade-offs.

7. QuestionMultiple choice

What does iteration mean in engineering design?

Please select an answer first.

Correct answer: C

The correct answer is Repeating design, testing, and improvement cycles.

  1. Identify the design problem: Determine the goal, criteria, constraints, materials, users, and evidence described in the situation.
  2. Evaluate the design process: Iteration uses test results to revise a design and test the improved version.
  3. Check the evidence: The correct choice is Repeating design, testing, and improvement cycles.

Iteration uses test results to revise a design and test the improved version.

8. QuestionMultiple choice

What is a trade-off?

Please select an answer first.

Correct answer: D

The correct answer is A choice in which improving one feature may reduce another feature..

  1. Identify the design problem: Determine the goal, criteria, constraints, materials, users, and evidence described in the situation.
  2. Evaluate the design process: Designers often balance cost, strength, speed, appearance, sustainability, and other competing goals.
  3. Check the evidence: The correct choice is A choice in which improving one feature may reduce another feature..

Designers often balance cost, strength, speed, appearance, sustainability, and other competing goals.

9. QuestionMultiple choice

Why should design criteria be measurable when possible?

Please select an answer first.

Correct answer: A

The correct answer is Measurements make it possible to compare solutions using evidence..

  1. Identify the design problem: Determine the goal, criteria, constraints, materials, users, and evidence described in the situation.
  2. Evaluate the design process: Measurable criteria allow engineers to determine whether and how well a design meets its goals.
  3. Check the evidence: The correct choice is Measurements make it possible to compare solutions using evidence..

Measurable criteria allow engineers to determine whether and how well a design meets its goals.

10. QuestionMultiple choice

Why should engineers consider the people who will use a product?
